Zusammenfassung:
Bis-perfluoropyridyl bridged by 1,4 and 1,2 dihydropyridine compounds was synthesized by reaction of 2 and 4 aminopridine derivatives with pentafluoropyridine. The structures were determined by X-ray crystallography. Compound 3a comprises two crystallographically independent molecules in the asymmetric unit in which one of them shows 1-D infinite chains along [0 1 0] direction due to the intermolecular C–H⋯N hydrogen bonds. In compound 5 intermolecular C–H⋯F and C–H⋯N hydrogen bonds link neighbouring molecules to each other. In addition, in both structures a series of C–F⋯π interactions stabilize the crystal packing.
